Cryptography Questions
Session key usage refers to the utilization of a session key in cryptographic protocols. A session key is a temporary encryption key that is generated for a specific session or communication session between two entities. It is used to encrypt and decrypt the data exchanged during that session, ensuring confidentiality and integrity of the information. The session key is typically randomly generated and is only valid for the duration of the session. Once the session is terminated, the session key is discarded, making it more secure than using a long-term key for encryption purposes.
